ORDER PINALES — PINAL ORDER 
Shrubs or trees. Leaves scale-like, narrow, or needle-like, and often

eate bracts, or in Taxaceae the ovulate flowers often solitary. Seed borne 
in a cone of dry or fleshy scales, or partly or wholly naked.—A group de- 
veloped later and more highly organized than the CYCADALES. 
Ovulate flowers several, with carpellary scales, these sometimes bracted: cone with 
either dry or fleshy scales. 
Carpellary a with bracts, not peltate: ovules inverted : buds scaly: wing
